Question

Find the nonpermissible replacement for y in the expression y+3/y+3

Answer 1

The non permissible value for y is y≠(-3)

Explanation:

In this question the given rational expression is (y+3)/(y+3) and we have to get the non permissible values.

Here denominator of the fraction should never be 0 otherwise the given expression will be undefined.

Therefore
`(y+3)\\eq0`

`y\\eq(-3)`

So the non permissible value is y≠(-3).

Answer 2

Non-permissible value is
`y=-3`

Explanation:

we are given equation as

`f=(y+3)/(y+3)`

we know that denominator can not be zero

so, we can set denominator =0

and then we can solve for y

`y+3=0`

we can subtract both sides by 3

`y+3-3=0-3`

`y=-3`

So,

Non-permissible value is
`y=-3`
